DNA primarily serves as a molecule for storing genetic information.
<h3>Functions of DNA</h3>
DNA refers to deoxyribonucleic acid.
It is a biomolecule found in the cells of virtually all living organisms. The molecule helps to store hereditary information.
DNA helps preserve traits across generations by the ability to replicate itself. Successive generations inherit copies of DNA through a complex process of gene expression.

Answer:
Cyanobacteria are responsible for first adding oxygen to the Earth's atmosphere.
Answer: Water and Carbon Dioxide
Explanation:
Plants use a process called photosynthesis to make food. During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch.
Macromolecules, or polymers, are formed by the combination of smaller molecules or monomers in a specific sequence. This is an energy requiring process called polymerization that produces water as a byproduct. Examples of macromolecules include nucleic acids, lipids, proteins and carbohydrates.
